I've been on my period for 20+ days. It will go from light spotting to very very heavy within a matter of minutes and there are large clots. I'm 22 years old, not sexually active as of about 3 yrs ago, and recently began working out a lot (I didn't know if that could have anything to do with it.) I hadn't had a normal period for about a year and a half and then all the sudden the flood gates opened. Any suggestions? Should i see a doctor immediately or could it wait until August? (My health insurance kicks in)
